Return to Castle Wolfenstein: Enemy Territory uses .dm_82 files to store recorded multiplayer gameplay sessions. The recording contains game data needed to reproduce the session during playback, not standalone video and audio.
The file belongs to the game's demo system and is normally kept in the Enemy Territory installation's demo directory.
The format is associated with the Microsoft Windows release of Enemy Territory and is intended for playback within the game.
Open a .dm_82 file with Return to Castle Wolfenstein: Enemy Territory on Microsoft Windows. Copy the file to the game's demo directory if necessary, start the game, and select it through the demo playback option or play it with the game's demo command.
The file cannot normally be opened as a video by a media player. The compatible Enemy Territory game version must be used for playback.
A .dm_82 file cannot be usefully converted directly to a standard video format because it is a game playback recording, not a video file.
To create a video, play the demo in Return to Castle Wolfenstein: Enemy Territory and capture the playback with suitable screen-recording software.
